Flipkart — Grocery items not delivered even after 3 days if promised delivery

I have ordered grocery items worth ₹1, 426 on 24th March 2022. It was promised to be a in two day delivery.
The order is not yet even shipped. And the support team is giving misleading information. The shipment tracking link
https://ekartlogistics.com/shipmenttrack/FMPP[protected] says its not yet shipped. But support team is saying that its shipped and I have to wait till next business day. Next business day being tomorrow, But they says next business day is whenever they will promise to deliver. Attaching the call audio to support team in malayalam language regarding this.
